I have experienced problems running the acpid service on TinyCore 6.3.
The version in acpid.tce is 2.0.8.
The daemon would just not start. There we no error messages or logs produced. The executable itself (/usr/local/sbin/acpid) would not produce any output whatsoever. Running the executable with the -d argument should produce some output in this case.
I have tested this in a virtual machine and on a FitPC2.
I have then compiled the latest acpid version 2.0.25 from the source (changing the ACPID_CONFDIR to "/usr/local/etc/acpi/evets" to point it the correct place according to the tutorials).
The latest version worked.
I haven't updated/submitted the tce with the latest version because I couldn't confirm that this issue wan't caused just by my setup.
